Somebody more computer apt than me can post the Perfect Vision review of the Ruby. The quality of the review on a scale to 1 to 10, with the WSR review being a 10, is a 1. The reviewer thought the Ruby was the product of the year, but IMNSHO his review was the worst quality review this year of any projector review I have read. He mumbled about having to have the projector screen center vertically to avoid keystoning (I guess he never found he vertical lens shift), that the projector had excessive white crush which I suspect resulted from him using his DVD player set to 0 to 255 output rather than setting it to 16 to 235 or other causes, and a reddish grayscale cured by calibration but he said if you didn't mind that, don't get it calibrated. I think he acknowledged that gray scale issues would vary from machine to machine. IMNSHO, this review is not worth the time it takes to read it. Pretty much useless info.
